I really only use polish when, I detail peoples cars on the side that have never seen any wax. I don't see ever needing to use a pure polish on the Crossfire, just clay twice a year and keep the Griots and Meguiars applied. Its used in combination w/ the clay bar, paint cleaner (which cleans below the paint surface) polish to bring out the color and hide swirls and the "finishing wax" to protect the above steps. Detailing cars for me is more of a "labor of love" for me. I just happen to make a little extra money on the side doing it.
